I have a few question. What the best software for DVD authoring ? How to make audio Dolby Digital 2.0 or DTS 5.1 ? Thanks
Sony Vegas and DVD Architect(packaged together) both have very powerful tools for creating audio, wether you want 2 channel stereo or dolby digital 5.1 surround sound. I find DVD architect easy to use, yet still very customizable. Once again you can only get DVD Architect when you purchase the Sony Vegas software, which is great for video editing.
I can't honestly answer that question, if someone doesn't respond, tryin googling and looking for reviews of both software. Then determine which software has more features, or and easier learning curve. Basically what would suit you best.
